Problem Installing Thermostat

Posted by AR on November 28, 2006, 2:21 pm

I have purchased a Hunter setback thermostat to replace the thermostat
that came with the house. I have run into a problem and have been
unable to get through to Hunter support.

Anyway, here is my problem. My current thermostat has five wires with a
jumper from RH to RC. The new thermostat says no jumper for 5 wires
and if I have a code letter on the existing thermostat of Y, C, or M I
should tag it Y/O. I have a C and a Y code with wires. What do I do
now?

Thanks

Do you have a furnace, or heat pump? What brand?

What are the colors of the wires in the wall?

What letters did they used to connect? Did Red go to the G terminal,
or to the X terminal? What was the old wiring setup?

Does your home have air conditioning?

What is the heat source?

Installing a thermost is often underestimated. More complicated than
it seems.

I have a Payne AC and forced air furnace.

Wire colors on current thermostat:

Blue to terminal C
Green to Terminal G
Yellow to terminal Y
White to Terminal W
Red to terminal RH

Black jumper wire RH to RC

No X terminal. It does have a B and O terminal but no wires are
connected.

I have installed thermostats before without any problem. This has
turned out to be a different story.

Should install just like the old one. Leave the RH-RC jumper in. Other
than that, it should be identical. I'd suggest to ignore whatever that
was in the instructions, and wire the new one like the old one.

Take it back to Lowes and get another one. It's defective.

Your next best bet would be to sand it down and then throw
acid on it.
